Rachana gzip compression

[RachanaZha]

Description

The website now includes gzip compression using the compression library. This middleware is configured to compress responses based on content type while considering streaming requirements and server load. Testers should verify that compression works correctly and evaluate overall server performance with and without compression enabled.

Main changes explained:

1. Added "compression": "^1.7.5" in the package.json file to include the compression library.
2. Integrated gzip compression in app.js using compression middleware. The configuration includes:
   • level: 6: Balanced compression level for performance and efficiency.
   • threshold: 0: Ensures all responses are compressed regardless of size.

These changes optimize response sizes to improve application performance and reduce bandwidth usage.

How to test:

Dont forget to npm install before building and running the application.

1. Run the application on localhost.
2. Before logging in, open the browser Developer Tools by pressing Ctrl + Shift + I.
3. Switch to the Network tab in Developer Tools.
4. Login to the application.
5. Observe the requests appearing in the Network tab (e.g., {i} users or {i} login).
6. Click on any request to inspect its details.
7. Under the Headers tab, locate the Content-Encoding field. It should display "gzip", indicating compression is applied.

I've reviewed this pr and the compression middleware worked as expected

Works as expected, the gzip Compression is applied. Not all Requests have gzip content encoding though, which I am not sure if it's supposed to be that way (please view the second image).

Good catch. All requests are supposed to have gzip compression. I'm opening this up for someone else to debug and check whats going wrong.
